DETAILED DESCRIPTION

[0018] Reference will now be made in greater detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.

[0019] FIG. 1 is a schematic diagram of marine illumination system 10 in accordance with the teachings of the present invention. Housing 12 includes inlet 14 and outlet 15. Marine apparatus 16 includes fluid source 17 which pumps fluid 18. Inlet 14 of housing 12 is in fluid communication with fluid 18. Fluid 18 flows in housing 12 from inlet 14 to outlet 15 through conduit 19. For example, fluid 18 can be water. In this embodiment, conduit 19 includes inlet 14 coupled or integral to outlet 15 through junction section 20. Inlet 14 is angled from outlet 15 in junction section 20. For example, inlet 14 can be angled at an Angle A.sub.1 range of about 90 degrees to about 120 degrees from outlet 15. In an alternate embodiment, inlet 14 is positioned substantially parallel to outlet 15 as shown in FIG. 2. For example, inlet 14 can be angled at an angle A.sub.1 in the range of about 120 to about 180 degrees.

[0020] Light source 30 is positioned in the flow of fluid 18 in the direction D.sub.1 towards outlet 15. Preferably, light source 30 is positioned between inlet 14 and outlet 15 so as not to reduce the area flow of fluid 18 within conduit 19 and to maintain substantially laminar flow of fluid 18 within conduit 19. Light source 30 can be a light-emitting diode.

[0021] The light-emitting diode can emit one or more colors. Example colors include red, blue, green, purple, orange and yellow.

[0022] Fluid source 17 can be bilge pump 50 as shown in FIG. 3. Fluid 18 can flow from bilge pump 50. Bilge pump outlet 52 of bilge pump 50 is in fluid flow communication with inlet 14. Fluid 18 from bilge pump outlet 52 is received at inlet 14. Light source 30 can be powered by bilge pump power source 54.

[0023] Fluid source 17 can be from watercraft motor 60. Fluid 18 can flow by pressurization from watercraft motor 60. Fluid 18 is received from outlet 62 of watercraft motor 60. Light source 30 is powered by watercraft motor power source 54.

[0024] Housing 12 can be permanently or removably attached to watercraft hull 70. Alternatively, housing 12 can permanently or removably mounted to watercraft motor 60 as shown in FIG. 3. Suitable mountings for housing 12 can include brackets, being supported by a plumbing connection, integral as a part of a water outlet, secured to watercraft hull 70 of watercraft motor 60 using a bonding compound or physical fastener.

[0025] In an alternate embodiment, light source 30 can be embedded in outlet 100 of watercraft motor 60 as shown in FIG. 4. Light source 30 is positioned in the flow of fluid 18 in the direction D.sub.2 towards outlet 100.

[0026] FIG. 5 is a photograph of a high pressure small diameter outlet from an outboard motor, with the water stream illuminated by the marine illumination system of the present invention. This condition is common for an outboard motor at above idle speeds.

[0027] For example, in this embodiment, outlet 15 can have a diameter in the range of about 0.1 inches to about 0.25 inches.

[0028] FIG. 6 is a photograph of a larger diameter outlet from a bilge pump with the water stream illuminated by the marine illumination device of the present invention.

[0029] For example, in this embodiment, outlet 15 can have a diameter in the range of about 0.375 inches to about 1 inch.

[0030] It is to be understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the principles of the invention. Numerous and varied other arrangements can be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope of the invention.
